Fishers two box has a reputation for being the best. Goes deeper, & traces farther!

Two box treasure hunters know that Fisher's Gemini-3 has a reputation for being the best there
is. Designed to locate deep objects; depending on ground mineralization and target size objects
may be detected as deep as 20 feet! The Gemini-3 goes deeper, traces farther and is easier to
use than any other cache finder in its class.

Detects all metals. Sensitive to large, deep objects or ore veins. Crystal controlled, 82 kHz transmitter and receive. Four mode operation: Inductive Trace, Conductive Trace, Wide Scan Inductive Trace and Narrow Scan Inductive Trace. Optional Ground Plate Assembly for long distance underground tracing 60 cycle noise reduction circuitry VCO audio target response for precision pinpointing

The biggest improvements in two-box metal detecting since the 1950s. Easier to use and 2 pounds lighter, it detects 10 - 20% deeper and traces most pipes and ore veins at least 50% farther than the Gemini 2 Two-box detectors find large, deep objects; ore vein; and pipes and cables. They are particularly useful for public utilities, geologists, prospectors, and professional treasure hunters.One person can use the Gemini 3 with the on-handle operation; two people can use it together to find long targets or ore veins. Search large areas quickly in “wide scan” mode, with two people walking up to 35 feet apart.
